Vintage WWII army officer lapel pins with original card and packaging

These are original WWII army officer lapel pins with original card and packaging. I believe these are brass. These were unused when I purchased them. I used them once for an army officer’s costume my son needed for a presentation for school. They are in excellent vintage condition. The original card is in very good condition. The original glassine paper packaging that it came with sitting behind the card is in fair condition given its age and the fragility of the material. From a smoke-free home with a dog.
